Overwhelmed by anguish and far from the comforts of family, Omar, a young Lebanese man, speaks via cellphone from a Canadian hospital with his pleading mother, who gently tells him how to go about performing the Islamic pre-burial rituals. Quietly devastating, ‘Light’ sidesteps melodrama, relying on tight close-ups, stilted conversations and Omar’s incomplete actions to illustrate his feelings of paralysis. Ahmed Muslimani provides a finely nuanced performance that conveys Omar’s desperation, fear and loneliness, and lays bare a grief so unbearable it defies his comprehension.
